fuzzy control active queue management input rate queue length
Considering the uncertainty of network model and time variability of network parameters,a fuzzy control active queue management algorithm based on input rate and queue variance is proposed.Using fuzzy control method,an exact model is not needed.Both load and queue of the network are concerned to speed up the perception of the congestion.Simulation results show that this algorithm can stabilize the queue length to the target value and its drop probability is less than random early detection algorithm and PI controller algorithm.
